[0029] A limiting device is provided on the supporting base 1;

[0030] The limiting device includes a die 7, a mounting seat 13 and two pull plates 12. The upper surface of the die 7 is provided with two mounting seat grooves 6. The lower end of the mounting seat 13 is in an inverted "U" shape. The interiors of the two mounting seat grooves 6 are provided with first limiting plate grooves 16. The outer walls on both sides of the lower end of the mounting seat 13 are provided with second limiting plate grooves 17. The interiors of the two second limiting plate grooves 17 are both slidably connected with limiting plates 15. The two limiting plates 15 are both in an "L" shape. The interiors of the grooves provided on the outer walls on both sides of the mounting seat 13 are both slidably connected with pull plates 12. The two second limiting plate grooves 17 are provided with a plurality of second limiting plate grooves 17. A plurality of second return springs 14 are arranged inside the mounting seat 13, and the grooves on the outer walls on both sides of the mounting seat 13 are respectively communicated with the interior of the corresponding second limit plate groove 17, and the two ends of the plurality of second return springs 14 are respectively fixedly connected to the outer wall of the corresponding limit plate 15 and the inner wall of the second limit plate groove 17, and the outer walls on both sides of the lower end of the mounting seat 13 are respectively slidably connected to the interior of the corresponding mounting seat groove 6, and one end of the two pull plates 12 close to the limit plate 15 both slide and extend to the interior of the second limit plate groove 17 and are respectively fixedly connected to the outer walls of the corresponding limit plate 15.

[0031] Among them, the upper surfaces of the four supporting columns at the upper end of the support base 1 are fixedly connected with a top plate 3, the upper surface of the top plate 3 is fixedly connected with a cylinder 4, the output end of the cylinder 4 slides and extends to the outside of the top plate 3 and is fixedly connected to the upper outer wall of the mounting seat 13, the two sliding rods slidably connected on the top plate 3 are fixedly connected to the upper outer wall of the mounting seat 13 at one end thereof, the upper surface of the support base 1 is fixedly connected with a forming mold 9, the outer walls on both sides of the forming mold 9 are provided with sliding block grooves 5, the insides of the two sliding block grooves 5 are slidably connected with sliding blocks 2, the upper surface of the support base 1 is fixedly connected with two fixing rods 11, the outer walls of one end of the two sliding blocks 2 are respectively slidably connected with the outer walls of the corresponding fixing rods 11, the outer walls of the two fixing rods 11 are both sleeved with first return springs 10, the two ends of the two first return springs 10 are respectively fixedly connected with the outer walls of the corresponding sliding blocks 2 and the upper surface of the support base 1, the inside of the forming mold 9 is slidably connected with a sliding plate 8, and the upper surfaces of the two sliding blocks 2 are fixedly connected with the lower surface of the sliding plate 8.

[0032] Furthermore, when using the device, it is started by connecting an external power supply, firstly, the cardboard is placed on the surface of the sliding plate 8, and then the die 7 is driven downward by the output end of the cylinder 4 to fold and indent the cardboard, and then the force exerted by the die 7 on the cardboard causes the cardboard to move downward, driving the sliding plate 8 downward while driving the sliding block 2 downward, and then the downward movement of the sliding block 2 drives the first return spring 10 to contract. At the same time, when taking out the folded and indented cardboard, the force exerted by the first return spring 10 on the sliding block 2 causes the sliding plate 8 to reset while ejecting the folded and indented cardboard.

[0033] Furthermore, when the die 7 needs to be removed, the pull plate 12 is pulled in the opposite direction to drive the limit plate 15 in the opposite direction, while driving the second return spring 14 to contract. Then, the limit plate 15 moves in the opposite direction to make the outer wall of its lower end disengage from the inside of the first limit plate groove 16, and then the die 7 can be removed from the mounting seat 13. In this way, the die 7 is limited by the limit plate 15, which effectively improves the installation stability of the die 7.

[0034] The pull plate 12 is pulled in the limit device to move in the opposite direction, driving the limit plate 15 to move in the opposite direction and driving the second return spring 14 to contract. Then, the limit plate 15 moves in the opposite direction to make the outer wall of its lower end disengage from the inner part of the first limit plate groove 16, so that the die 7 can be removed from the mounting seat 13. In this way, the die 7 is limited by the limit plate 15, which effectively improves the installation stability of the die 7, thereby avoiding the loosening or displacement of the die 7 due to the force generated by the vibration of the equipment during the production process, thereby improving the stability of the equipment. The first return spring 10 is driven to contract by the downward movement of the sliding block 2. At the same time, when taking out the cardboard with a good folding indentation, the force generated by the first return spring 10 on the sliding block 2 causes the sliding plate 8 to reset and eject the cardboard with a good folding indentation. This makes it easy to take out the cardboard with a good folding indentation, effectively reducing the workload of the staff and improving the work efficiency of the staff.

[0035] Working principle: first, place the cardboard on the surface of the sliding plate 8, then drive the die 7 to move downward through the output end of the cylinder 4 to fold and indent the cardboard, then the force exerted by the die 7 on the cardboard causes the cardboard to move downward, driving the sliding plate 8 to move downward while driving the sliding block 2 to move downward, then the sliding block 2 moves downward to drive the first return spring 10 to contract. At the same time, when the cardboard with the folded and indented pattern is taken out, the force exerted by the first return spring 10 on the sliding block 2 causes the sliding plate 8 to reset while ejecting the cardboard with the folded and indented pattern. Then, when it is necessary to remove the die 7, pull the pull plate 12 to move in the opposite direction, drive the limiting plate 15 to move in the opposite direction, and drive the second return spring 14 to contract. Then, the limiting plate 15 moves in the opposite direction to disengage the outer wall of its lower end from the inner part of the first limiting plate groove 16, and then the die 7 can be removed from the mounting seat 13. In this way, the die 7 is limited by the limiting plate 15, which effectively improves the installation stability of the die 7.
